The historic Montparnasse brasserie La Coupole was also a popular dance hall during Les Années Folles. Over the past 20 years Le Dancing de La Coupole has been transformed, updated, outdated, closed, reopened, and closed again. And since September they are once again hosting thés dansants every Sunday afternoon from 2:30-7pm, with the dance floor open to tango, salsa, cha-cha, rock (swing), fox trot, rumba, etc. Entrance is €18, coat check €1 per item (obligatoire).
